CAN-SOLDERING, MACHINE.

SPECIFICATION forming part of Letters Patent No. 295,210, dated March 18, 1884.

' application filed August 9, 1853. (No model.)

.To all whom zit-may concern:

Be it known that I, JOHN A. TILLERY, a citizen of the United-States, residing at Baltimore, in the State of Maryland, have invented 5 certain new and useful Improvements in Can- Soldering Machines, of which the following is a specification.

My invention relates to a can-soldering machine having certain features of improved construction,as hereinafter described and claimed.

In the drawings hereto annexed, Figure 1 is a vertical section. Fig. 2 is atop view. Figs. 3 and 4 are views of the detachable covers for the flame-chamber. Figs. 5 and 6 are front Fig.7 is a View of the casting separate, which forms the flame chamber.

The letter A designates the top plate, made preferably of cast-iron. This plate has circular 2o recesses b sunk below its top surface. Thelower side, I), of each recess depends below the lower en rface of the plate. Each recess is adapted as a seat for the end of a cylindric can. Abottom plate, G, extends below all the recesses, leaving a narrow space, cl, between the two plates for the passage of flame, smoke, and heated air. At each of two opposite edges the top and bottom plates are connected by a strip, 6, thereby closing the space along those edges; but the space is opeh at the other two edges-- that is, the upper andloweredges, (indicated by d and d The two plates are supported on legs f f, and have an inclined position. At the lower part of the inclined top plate a square flame'rcceiving chamber,G, is formed, which is independent of the space between the two plates. This chamber has an upward-sloping rear wall, 71, and a narrow horizontal opening, 2', at the top of the wall, which places the chamber and the flame-passage d in communication. The burner j projects its flame into the chamber G, where the greatest part of the heat is confined, and the flame-strikes the upwardsloping rear wall, h, which favors its rising andpassing the opening 2'. The bottom, sides, and upwardsloping rear wall constitute a single piece of casting, (see Fig. 7 which, when attached to the lower side ofthe top plate, forms the chamber. The bottom has a stud,

It, cast with it, which serves as a bearing for a rotary can-seat, Z, the plane of whichis below the top plate, and on a line direct with the narrow horizontal opening Mending from chamber G into the flamepassage d. At each side of the chamber G is an opening, (1, for air to 55, enter the flame-passage (Z. This arrangement serves to intensify the heat under the sunk recesses b. The top plate has a circular opening, on, in which the end of a can is placed, the can resting on the rotary seat I, the top of 6 which is below the opening. By this arrangement the circular opening centers the can on the rotaryseat and sustains it in position there, while the flame in chamber G has access to the flange of the canbottom, and the flame can 5 pass all around the can-cylinder, being confined below the top plate, and thence passes the narrow horizontal opening i into the flamepassage (Z. By my arrangement no flame or smoke escapes above the top plate to soil the cans-or annoy the operator, and as the sunk recesses depend into the flamepassage (1 they get the full benefit of the heat, and thereby the cans, when occupying these recesses preliminary to being soldered, are thoroughly heated. The can should have the side seam of its cylinder soldered and the top and bottom placed in position ready to be soldered. A piece of solder sufficient for one end is then placed inside of the can, which is set into one ofthe recesses to be heated. The can is then trans ferred to the rotary seat and turned thereon by the workman. The flame here applies itself to the flange of the can'bottom and the solder sweats through to the outside. Another piece of solder is then used in like manner to'solder the other end of the can.

The sunk recesses may be of a size suited for the largest ordinary can-say a three-pound can-which will also receive any smaller size. To adapt the machine for the various sizes of cans, that part of the top plate above the chamber'G, which has the circular opening m, is made detachable. This detachable cover 12- to chamber G (see Figs. 3 and 4) has a hole or opening for a can of given size. A separate cover is required for each size of can. It is simply necessary, therefore, when about to make a different-sized can, to remove the detachable cover a and place one in position hav- Ice ing an opening of proper size. A rotary seat suited for the smallest can'will thus serve for all the other sizes.

Having described my invention, I claim and desire to secure by Letters Patent 0f the United States- I I 1. A cansoldering machine embracing the following construction, to wit: an inclined top and bottom plate, with aflamepassage, d, between the two plates, a flamereceiving chamber, G, at the lower part of the top plate, having an upwardsloping rear wall, h, and a narrow horizontal opening. 2', at the top of the wall, and a rotary seat, Z, the plane or top of which is below the top plate and on a line direct with the narrow horizontal opening, as set forth.

2. A can-soldering machine having an inclined top and bottom plate, with a flame-passage, d, between the two plates, a flame-receiving chamber at the lower part of the top plate, having an upward-sloping rear Wall, h, and an opening, 1', at thetop of the wall, and a separate air-opening, (1, into the flame-passage at each side of'the flame-receivingchamher, as set forth.

3. A can-soldering machine having an inclined top plate provided with circular recesses b, depending below the lower surface. a bottom plate with a flame-passage, d, between the two plates, a flame-receiving-chamber at the lower part of the top plate, having an upWardsloping rear wall, h, and an opening, t, at the top of the wall, and a separate air-opening, d, into the flame-passage at each side ofthe flamereceiving chamber, as set forth.

4. A can-soldering machine having an inclined top and bottom plate, with a flame-passage, (Z, between the two plates, a flame-receiving chamber at the lower part of the .top plate, provided with a rotary seat, Z, and a detachable cover, n, for the chamber, having a circular opening, as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
